CVE-2025-10256
MEDIUMFFmpeg 3.2-8.0 - Denial of Service via Firequalizer Filter NULL Pointer Dereference
Title source: llmDescription
A NULL pointer dereference vulnerability exists in FFmpeg’s Firequalizer filter (libavfilter/af_firequalizer.c) due to a missing check on the return value of av_malloc_array() in the config_input() function. An attacker could exploit this by tricking a victim into processing a crafted media file with the Firequalizer filter enabled, causing the application to dereference a NULL pointer and crash, leading to denial of service.
